Step 1: Preheat oven to 180°C. Line a baking tray with baking paper. Place sweet potato on tray, spray with oil and bake for 25 minutes, or until golden and tender.

Step 2: Meanwhile, place macadamia nuts into a food processor and blend until very finely chopped. Sprinkle one side of each lamb steak with nuts and press lightly to secure. Season with freshly ground black pepper.

Step 3: Spray a large frying pan with oil and place over medium-high heat. Cook lamb for 7–8 minutes, turning halfway through cooking, or until cooked to your liking.

Step 4: Meanwhile, steam all three types of peas until tender. Add spinach and toss gently to combine, until wilted. Serve pea mixture with lamb and sweet potato chips.
